COEB-UGATED-PAPER-BOARD MAOEINE' Specification of Letters Patent.

Application filed August 15, 1917. Serial No. 186,263.

' provide improved means for ironing and drying the board after the second facing sheet is applied, for insuring proper contact of said facing sheetand the tops of the corrugations at the time of drying so that the board shall be as firm and strong as possible.

My invent-ion also embodies improved feeding means which operate in conjunction with the improved ironing means and a suitable heater.

With these and other objects in View, which will appear as the description progresses, I have illustrated the invention in the accompanying drawings, in which,

Figure 1 of the drawings is a side elevation of a portion of a corrugated-paperboard machine embodying my improvements.

Fig. 2 is a plan of the same.

Fig. 3 is a detail section of the line 3-3 of Fig. 2.

Fig. 4 is a detail of the feed mechanism, and

Figs. 5 and 6 are detail views of the means for disconnecting the ironing and feeding means.

Similar reference characters refer to corresponding parts throughout the several views.

The first two figures of the drawings illustrate a portion of a corrugated paper machine into which the paper board is passed as soon as the second facing sheet is applied to the single-faced corrugated paper board with the silicate or adhesive still damp, intermediate portions of the machine being broken out to allow the drawing of the parts on a larger scale. The frame of the machine maybe made in any suitable way and is here shown constructed with a pair of side frames such as 1, mounted on legs 2, and suitably connected as by transverse members 4. Any suitable heating medium can be used, as for instance live steam in a suitable heater such as H, which is preferably composed ofa series of sections 5,.that can be supported on the frames 1 in any suitable way as by longitudinal members 6.

Steam'pipes 7 and 8 connect the sections 5 to the mains 9 and 10 at the ends of sections 5 and the tops of the latter are here shown is forming a practically continuous flat surace.

My improved ironing means embody a multiplicity of members for rubbing and pressing or ironing the composite sheets onto the top surface of the heater and these ironing members may be arranged in any suitable way such as in a series or elongated group arranged lengthwise of the machine, and I find it very advantageous to arrange the machine with a plurality of these groups side by side so that the ironing may be more thoroughly and efficiently done. I also arrange the individual units in ranks across the machine, so that by having the units of the same size and in ranks, the several groups will together form a rectangular group or apron, which 1 connect by suitable devices, designating the apron generally by the letter A.

Any suitable ironing units can be used, but 1 preferably employ fiat metal plates such as 11, with suitable connecting means such as bolts 12, in angle pieces 13 on the ends of the plates, with spacing tubes 14 on the bolts.

. I also find it advantageous to be able to ,adjust the heights of the plates or units, and

suitable means may be employed forthls, as for instance, rollers 15 extended across the machine, and these rollers supporting the plates by the spacing tubes 14, which rest in grooves 16 in the rollers. The rollers are supported by adjustable guides 17, secured to the ends of the heater sections by bolts 18, in slots 19, and adjusted by screws 20. The whole ironing group orapron has a certain flexibility throughout which. allows the units to adjust themselves. to slightly varying thickness of the drying paper board. I provide suitable means to give the plates a rubbing action on the paper board and preferably do this by giving the plates or units simultaneous reciprocating movements. Any suitable means may be employed to accomplish this, but the means I prefer to use embodies the following mechanism: I provide a bar such as 21, which is connected to the left hand plate of each longitudinal series or group, and rests on adjustable guides Mounted on the frames 1 near the bar 21 are pedestals 23, in which isjournaled a shaft 24, and on the shaft are rocker arms 25, suitably secured thereto and connected by links 26 to the bar 21. shaft 24, and connected by a link 28 to the crank pin.29, on the gear 30, which is mounted on the shaft 31, and said shaft turns on suitable bearings 32 mounted on the frame 1. The gear is driven by means of the gear 33 on the shaft 34 of the feed roll 35, which is driven by suitable driving means (not shown).

The paper board is delivered to the left 1 hand end of the heater H by the feed hen 35 and suitable means are provided to advance the end of a sheet of paper board up to and into the grip of the drawing rolls 36, which rolls are driven by suitable means (not shown).

The means I prefer to employ embody a plurality of arms 37 pivoted on pins 38, mounted in brackets 39 on the bar 21. The said arms 37 have toothed wheels 40, which in their normal position engage the paper board with their teeth and move it to the right when the bar 21 is moved in that direction but release it when moving to the left, the said wheels 40 being free to move in the direction in which the paper board is fed but prevented from turning backward by pawls 40 mounted on extenslons of the arms 37 and engaging narrow ratchet teeth 40 at one side of the wheel 40.

Journaled onthe shaft 24 are bars 41 having serrations at their free ends, which prevent the backward movement of the paper board under the rubbing action of the reciprocating plates 11. The feed arms 37 can be disengaged from the paper board when desired by turning the handle 42, secured to the shaft 43, which shaft is mounted in brackets 44 on the bar 21 and provided with set screws 45. The set screws engage extensions of the arms 37 when the handle 42 is turned and raise the arms 37 and wheels 40 to disengage the latter from the paper board.

It is sometimes desirable to remove the ironing group or apron A for the'purpose of cleaning it, and I provide means whereby it can be readily disconnected from other parts of the machine. Any suitable means may be employed to effect this disconnection, such as those illustrated in detail in Figs. 5

- and 6, in which the links 26 are connected to the bar 21 by detachable studs 46 and normally held in place in holes 47 at the ends A third rocker arm 27 is secured to the' meas es of said bar 21 by removable pins 48. When it is desired to disconnect the apron A, the pins 48 are pulled out and the studs 46 are then to be removed, allowing the apron A to be taken off the heater H.

In operation the paper board passes into the above mechanism over the revolving feed roll 35 onto the left hand section of the heater H and under the extreme left hand plates 11 which are provided with upturned left hand edges. As soon as the paper board passes under the toothed wheels 40 on the arms 37, it is moved to the right intermittently as said arms and wheels are reciprocated on the bar 21 through the action of the gears 33 and 30, crank pin 29, link 28, arm 27, shaft 24, arms 25 and links 26. This intermittent movement of the paper board cOntinues until its front edge is passed into the grip of the rubber-covered drawing rolls 36, upon which the arms 37 and wheels 40 may be moved out of action, and the drawing rolls then operate to feed the paper board continuously.

Whenever the paper board is passing under the plates 11, these are rubbing and pressing or ironing it against the fiat top surfaces of the heater sections 5, causing close contact to be made between the tops of the corrugations and the facing sheet just applied, while the silicate or adhesive is drying, so that the board shall be firm and strong.

The plates 11 are adjusted by means of the set screws 20 to a height that insures firm I contact but will not crush the corrugations, and the weight of the plates 11 and their attachments is arranged to give the right pressure for good contact of the facing sheet joining units, and means for reciprocating.

the apron lengthwise of the heater.
